I have posted previously about ThingLink.com and the great options it can bring to a research project. You can read about it here. A month or two ago they came out with a ThingLink app that works alongside the website.
Like the site it is easy to use. You do not have all the options available on the app at this time. Currently, you can only add text and link to video when using the app. I am hoping more of those options will become available as the app is updated.
Create an account or log in with your current account. Take a picture or choose an image from your library, then click on the image where you want to add your information. Add as many targets as you wish. When you are through, title your image and you are ready to upload it to their site. You can post directly to Facebook and Twitter, or choose to email a link directly from the app. If you want to embed your product, you will need to go to the website for the code. It is a great way to share information with your students or let your students show what they have learned.
